MSD advance bushings for pro billet style distributors. The bushing in an MSD system are limited to 18 degrees. The MSD supplied bushing sometimes don't allow for initial timing the engine wants without pushing your total number out of bounds. These solve that issue by allowing 4 or 8 degrees more initial timing.
Bushings are cut on CNC machinery and work well. Easy to install and change as needed.
